Short description of error
3D View navigation freezes - zoom stops working
Exact steps for others to reproduce the error
Load Factory Settings
Go to File -> User Preferences and enable the following options:
[Interface tab] -> - [x] Zoom To Mouse Position
[Input tab] -> - [x] Emulate 3 Button Mouse
[Input tab] -> Orbit Style: Trackball
[Input tab] -> Zoom Style: Horizontal

At some point zoom will completely freeze - it won't be possible to zoom any further. Trying to zoom out won't work either - zoom is now completely frozen :(
Workaround
Press dot/comma on numerical keyboard to focus view on selection or just press SHIFT+C
Note
This bug has 100% reproducibility

Can confirm. Not sure what the root of the issue might be, assigning to me for deeper investigation.

Well. That is not really a bug. It has been like that since like forever. It is because it is a zoom in 3D, not a dolly. Think of using a Tele lens. At some point there is just not enough focal length anymore. Pressing the Dot key will reposition the virtual viewport camera, so that you have enough zoom available. At least that is how I think it works. There is however an alternative: Using dolly zoom, which is Ctrl+Shift+MMB (Or Ctrl+Shift+Alt+LMB in your case).
This whole zooming thing is a bit crappy, but well, it has been like that since forever.
@sebastian_k, agree, but shouldn't it be possible to zoom out again? ;)
I can't reproduce the "stuck-ness" really. If I have zoomed in too much, then yes, sometimes it can take a fair bit of zooming out to see an effect, but eventually the zoom will work again at some point.
I can't really argue whether this should be treated as bug or not. This particular configuration is 100% compatible with Modo (The Foundry's product) and zoom getting stuck is rather a serious drawback because it's impossible to navigate freely in 3D. I personally need to press dot/comma constantly to reset zoom... Even if it has been like that since forever, maybe it'd be good to treat it as bug nevertheless?
BTW: if it's really tele lens just like Sebastian suggested, why does it allows me to move inside the object? :)

You can also use the home screen key to reset the screen

This could be a design issue, except no solution is proposed, sounds like the reporter is expecting zoom to dolly, in that case just use dolly.
Some explanation/discussion - http://blender.stackexchange.com/a/651/55
I can confirm that enabling Auto Depth option (on the Interface tab) is a great workaround! Everything now works without any issues. Perhaps it'd be good to make this option enabled by default in the future release?
@Mission - the reason we don't enable by default is it means you have to consider cursor placement before doing any view operations.

This thing has been happening to me for ages, and it is very frustrating because it happens all the time. I also already tried some of the solutions above but none of them worked for me so far.
